I IMPROVEMENT l N GATES.

Specification forming part of Letters Patent No. 194,682, dated August26,1877; application filed April 16, 1 875.

To all whom it may concern: i 1

Be it known that I, ROBERT HENRY HUD- GIN, of the town of Whitby, countyof Ontario and province of Ontario, Canada, have in vented Improvementson Farm and Garden Gates, of which the following is a specification r Myinvention relates more particularly to certain improvements in thatclass of gates upon which 1 have already secured patents on the 24th ofJanuary and 13th of February, 1871, and 2d of July, 1872; and isdesigned with the view of providing a strong farm-gate which can beinstantaneously raised and lowered, as desired.

In Figure 1, Sheet 1, of the accompanying drawing, A is a reargate-post, on'which the gate hangs. b is the front orlatch post; 0, ahead-block, about ten or twelve inches in length, a trifle thicker thanthe gate, and about five inches broad, with a tongue on the middle ofthe front side, designed to work in a suitable groove in the rearupright bar of the gate, which steadies the block when the gate is beingraised or lowered. l is a pintle-bar, of tough, hard wood, spiked orbolted onto the face of the rear gatepost A.

Fig. 4 is a cross-section of the pintle-bar, the grooves being next tothe post. These grooves receive the ends of the bars N, holding them inplace, and are shaped so as to suit the curve described by the bars asthe gate is opened and closed.

D D are light rods of iron, called suspensionarms, fitting in thehead-block 0 near the rear edge, and extending thence diagonally towhere they engage with the gate on the upright M, the front edges ofwhich are suitably beveled. H is a drop, designed to prop the gate open.F F are latch-bars.

It will be seen that the gate is held up by the suspension-arms D D, andsteadied at the bottom by the bars-N. The rear part of the gate, beingthe heavier, freely slides down between the arms D D till it bearsagainst the block G, which tightens the gripe of the arms and preventsit sinking further. The acute angle of the arms when inserted in theheadblock, and the weight of the gate upon them,

causes them to be drawn firmly against the sides of the block 0, andtheir connection being near the rear edge, they act like a band,efl'ectually securing the block against being split by the weight of thesaid gate.

Fig.2 isamodih'cation of my iron head-block Q and pintle. O is a webconnecting two sides of the block, and is about three and one-halfinches long by three inches in width and threefourths of an inch thick.In the center of this Web, and extending about one-half way down, is theprojection 10, which is cup-shaped at the bottom to suit the point q,being a cast-iron pintle with the shank r, to be inserted into a post atan angle of thirty degrees downward to the dovetailed shoulders, as seento the lefthand side of the letter 1'. On each side of the web 0 thesides of the block (J extend about three-fourths of an inch in front andrear of it. The front projections form a recess in which the rear of thegate is steadied, while the rear projections form a base, into whichholes are made for connecting the iron arms 10, as seen in the samefigure. The iron pintle, as seen to the right in Fig. 2, is also shownin Fig. 5 on a smaller scale, designed for a small garden-gate. Theshank r is to be driven in a suitable hole till the dovetailed shouldersto the right bed or interlock with the wood of the post, which leavesthe point q in. a perpendicular position.

It will be readily seen that the pintle thus diagonally inserted cannotbe withdrawn by the weight of the gate, which only increases itsadhesion to the post.

10 is the cup-shaped projection described in Fig. 2, having a shankformed to the right, which is to be inserted in the rear upright of thegate at an exact reversed angle to the shank r in the post.

I will only add that the gate opens both ways and closes automatically,is a snow-gate, and cannot droop at the point, and can be constructed atone-half the cost of any other rotating gate without the use of thesuspensionarms.

The post shown in Fig. 3, Sheet l,and fence exhibited in Fig. 5, Sheet2, were specially designed by rne for the gate herein described,

and I reserve the right to secure them in a fuwith projecting ends tofit upon the said pintle ture application. I, substantially as and forthe purpose speci- I claim as my inventionfied.
